I've run about 5 hour with this setup before the controller catch in fire.

Don,t know the reason

6s lipo is presumably 6 cell which at 3.7 volts per cell equates to 22.2 volts, the 16018 is rated as per model number suggests at 18 volts so your running it over it's limit. I was going to go with the 16018 until I realised that it would restrict me 4/5s so I ordered the 16025.
This may not have been your problem but I wouldn't rule it out.

Sorry but you're not right my friend, the 16018 is rated for 6s li-po or 18 cells ni-mh.
18 cells ni-mh = 21.6V
6s li-po = 22.2

The 16018 can support 25V.

So i was not running over limits

Today, i've plug the pack and give it a little run, and in about 3 second after niail the trottle, ........... Poufffffff!!!! some white smoke around the revo. So i remove the body to see a beautifull and big, big flame on the controller
I've un-plug the li-po to save it from the fire.

The negatif input lead have boke inside of the board and short on the input capacitor.

I hope that my 2 li-po pack are correct, i've not try to recharge it.

So i nead a new controller. Maybe a MMM or another MGM i don't know.

David,

Forget the MGM!!! Cut your losses and go with the MMM.

It worked for a while after that only on external BEC or RX pack, and then it shot some little flames when the fets went up.

I had exactly what David and yourself have explained happen to me. Sad thing is when I sent the unit back to MGM for a warranty repair I was slugged with a $120 (AU) repair bill . I will be selling my MGM when it gets back and getting a MMM as soon as Mike has them readily available.

Cheers Andrew

the "18" number isnt the amount of voltage it can take but the number of NiMh cells it can handle....so the voltage was fine

My mistake s I apologise, I'm sure it won't make any difference in that case but as MGM have a 16025 listed I went with that instead of the 16018, it'll probably still go up in smoke at some point!
